Tele Vue Nagler 7mm Type-6 Eyepiece 1.25"
- Product Code: eq7058
-
Based on the original Nagler design, the 7-element/4-group lens configuration employed in the Tele Vue Nagler 7mm Type-6 Eyepiece 1.25"was designed as an ideal eyepiece for lunar and planetary viewing.
Despite its short focal length, the optical properties allow it to maintain its wide 82° apparent field of view, and a comfortable 12mm eye relief that provides space between the lens and eye to prevent accidental contact that can interfere with views. Built to Tele Vue's exacting standards, the Type-6 features anti-reflection fully multi-coated optics to improve brightness, color rendition, and contrast; and a fold-down rubber eyecup that helps to block stray peripheral light from interfering with the views and to further enhance contrast. A textured collar around the body ensure safe handling in the cold or while wearing gloves. The Type-6 has a barrel diameter of 1.25" to fit into the most common sized focusers and accessories, and is parfocal with all Tele Vue group 'B' eyepieces, allowing you to change eyepieces within the group without having to refocus every time.

Related Questions and Answers
Q: 1. what is the percentage of distortion.....?
A: It would really all depend on the Telescope you have. Unfortunately I do not have that type of information, my apologies.
Q: 2. Can this be used with Celestron 102 AZ telescope ?
A: Yes, the Celestron X-Cel LX 7mm Eyepiece (1.25"), can be used with the Celestron 102 AZ telescope.
Q: 3. Is this a good eyepiece and is it compatible with the Celestron Nexstar 105 GT telescope?
A: Televue Panoptics are excellent eyepieces. Very sharp, clear images. To determine if an eyepiece is compatible with your telescope you first need to calculate your telescope's Maximum True Field of View, then calculate the eyepiece's True field of View. Eyepieces that have a True Field of View greater than your telescope's Maximum True Field of View will cutoff the image and have chromatic aberrations around the edges. Generally speaking, it does not hurt to go a little over tFOV with quality eyepieces, but the more the eyepiece's tFOV is over the telescopes's max tFOV more of the image is cutoff and the worse the chromatic aberrations get around the edges.There are several very good free eyepiece calculators available on the web to calculate Max tFOV, and help determine eyepiece compatibility.
Q: 4. Hi.. Hello,How can I use this eyepiece with Canon Kiss-X2?
A: It should work if you have the correct Canon T-Thread adapter for your Kiss-X2
Q: 5. What I feel that needs to be better explained about eyepieces and focal lengths as in 6mm or 25mm is that the opening is tiny for 6 mm as compared with 25mm that is wider . The lower the focal length the difficult it gets to train your eye throughthe opening due to its tiny opening. My child experience with my first kid telescope that came with 6mm and 25mm eyepieces told me that 25mm is more enjoyable to use despite lower magnification than the higher magnifying 6mm which is so restrictive in the opening for my eye to keep peeking through as steadiily as I can. I think that a minimum of 10mm is acceptable to me or maybe 12mm. . Am I correct?
A: Yes that is correct. 10 or 12mm will be okay. It also depends on how large of an aperture your scope has. The bigger front opening of the scope the brighter the image.
Q: 6. Is it advisable to use a barlow lense with Televue eyepieces?
A: This is a fairly high powered Eyepiece. I would only go with a Barlow if you had a Scope with a large Objective around 8", and up.
Q: 7. How will this TV 32 mm plossl work in a Celestron C5 spotting scope?
A: The Celestron C5 127mm f/10 50x Spotting Scope (OTA Only) BH #CEC5SB • MFR #52291 came with a 25mm eyepiece The Tele Vue Plossl 32mm Eyepiece (1.25") BH #TEEPL32P • MFR #EPL-32.0 is a upgrade eyepiece becaus og better glass and coatings on the elements
Q: 8. Could I use this with my Meade 125 etc?
A: If your telescope has a 1.25 eyepiece opening then this eyepiece will work. To determine if your scope does I will need to know the exact Meade Model that you have.
Q: 9. Hello,Is this lens compatible with the Celestron 6SE telescope?Many thanks
A: I bought the lens about a month but have no chance to view through it yet. However I did try fitting it to my Celestron 8SE telescope which has a 1.25 diagonal and I did not have any problem.
Q: 10. are the Delos series eye pieces par-focal?
A: Yes it is. This is parfocal with Tele Vue Group B eyepieces so no refocusing is required when switching between eyepieces within the group.
